I am Jivi and i want to start a new project since i got a HP Compaq DC7100SSF from a freind of mine and i want to try if OSX will run on this machine i know this machine is kinda old but still i am intresting in what the power of it can be. I am not new whit osx86 since i already got a HP NC6320 running osx pretty well i used IPCOSX10.5.6 for this laptop and i am going to use IAKTOS S3 10.6.3 for the DC 7100. oke so lets start whit the Specification of this DC7100:

ProcessorIntel Pentium 4 2.8 GHz

Memory/ 2.0 GB DDR2 667MHz Dual Channel SDRAMKingston Memory

Hard Drive80.0 GB

Optical DriveDVD-ROM IDE working installed the osx whit this drive

Graphics ProcessorIntel GMA900 working whit modified GMA950 kexts

Cache TypeL2 cache

Cache Size1.0 MB

Ethernet. BCM 5751 LFB worked whit BCM5751 kext

Wireless Ralink USB 150 MBPS came whit drivers for OSX on the cd.

oke so you can find the IAKTOS S3V2 at their forum google it.

i have burned the ISO onto a DVD-R at the lowest speed 4x using imgburn.

the computer booted up whit out using any flags!

i have formated the hard disk OSX Extended Journaled( MBR) this because i will use a litle program EasyBCD to fix the MBR to dual Boot into Windows!

now comes the tricky part here you have to customize your hardware, Boot loaders, kernels, patches,and configure your VGA and Ethernet.

to succeed in this part you will need to know your hardware if you do not start looking into it.

to get the GMA Graphic Card working you can check out these posts they were very helpfull!

I recently added a Asus Geforce 7500 LE as a Graphics card to the system and i now have wonderful Graphics whit this cards everything works QE/CE resolution up to 1080 tested on my Samsung TV connected trough DVI.

i Updated the system to 10,6,8 trough the software update in OSX it self now i the machine hangs at this message [ PCI configuration begin ] and wont load any further i haven't gotten past this message looking into it still i haven't gotten past this message so i reinstalled Iaktos S3 V2 i used the following options in customize:

Boot loader i chose

AsereBLN v1.1.9

Bootloader options i chose:

32 bit boot

ethernet

patches i chose:

/extra directory

fake SMC ( this is a Must)

disabler

RTC drop down the menu and choose RTC (32BIT) this is a must because our cpu is not 64bit!

modified kernels i chose: qoopz 10.3.0

UUID select this

Drivers i chose:

SATA/IDE

dis-select the sound we will add these later since these give alot of kernel panics installing the wrong sound driver.

select PS/2

VGA only select these if you know what you need to select otherwise dis-select this i did not select this!

now continue installation this will take up to 30 minutes you do not need to stay whit the computer.

once the installation is done you have successfully installed OSx onto your HP Compaq DC7100 congratulation!

for your first boot up i recommend to boot whit flag -v -f this always worked for me though.

if your computer does not boot try these flags cpu=1 ncpi=0x2000 these might work otherwide try graphics enabler=no

this link is very helpful it has almost all the flags you could use trying to boot your OSX instalation.

this is a very straight forward setup to get from 10.6.3 - 10.6.8 i got everything working whit the information provided by this tutorial i did not succeed into getting QE/CE whit the GMA900 card though but i have seen and read that it is possible to get it working. since i am using a PCIE Asus Geforce 7500 LE I didn't need the GMA900 kexts but search the web and you will succeed!

so now that i have an osx 10.6.8 running machine whit almost everything working now my computer wont shut down or restart properly it closes down OSX but the computer PSU stays on whit a black screen i am still looking into fixing this problems if anyone knows how to fix this your help is much appreciated pm me or post it so more people can enjoy this fix.

so this osx build was an success i also build a laptop HP NC6320 if you want to know more about the laptop build let me know and i will push you in the right direction i hope i was able to help some people to give an old machine some life since this machine runs terrible and slow on Windows 7 and windows 8 and windows xp isn't that fine either. i will provide a zipped archive file whit the Kexts i used for this build and i hope they will help you out i did not make these kexts i just found them trough research on the net so do not ask me for any help customizing kexts .

oke so i found the kext for the audio driver wich is an Soundmax AD1981B ICH6 you can find the driver in this post. the kext is included in the attached archive!

I would not bother with that old, basic and obsolete GMA900 under SL, stick to your supported PCIe x16 graphics card, you'll get far greater performance.

Re: kernel, you should get very good results with Nawcom's legacy kernels too; he made one for every SL update that got out. I use them on all my legacy systems and they all work great under SL 10.6.8.

Hey Hervé thanks for the post i was wondering if you could tell me or point me in the right direction why the computer has got an restart/ shutdown porblem i cant seem to get this solved i have done the Evoreboot.kext instal in extra folder using kextwizard what allot of people described this did not work for me, and the computer would shut down properly in osx 10.6.3 hope you can help me out there.

thanks allot though and yeah whit the Geforce 7500 LE i get very good graphics performance for this old machine i am using it now as my Home theater computer to watch movies it works great even whit HD movies.

I can tell you, Hervé, these HP systems are not scrap... I'm a proud owner of DC7100 CMT Hackintosh... jivismacosx, upgrade the RAM to 4Gb... It makes os go very smooth. Mine DC7100 has a ASUS EAH6850 DirectCU v2... And BD-RE drive... I hope your PC works as well as mine. Also a SSD would be good performance upgrade for your system. I just have to get da money for a ssd...

My sound works with AppleAC97.kext.

i have now upgraded the memory to 3 gigs of ram and the performance did increase allot thanks for pointing that out a SSD would be amazing for this build but i think its a little to much for what i am using this machine i have now gotten XBMC Eden running on the machine and this works like a charm i can do all my Home theater stuff whit it and no glitches like it would have on windows 7!

but the main question is i have still got the restart and shutdown problem the computer just wont shutdown properly i have done allot of research but have not yet found the solution to this problem can you tell me if you have this too or point me in the right direction that would be great thanks in advance!

overall this machine works like a charm i am writing this post from the build i got my self a PC Remote control which works great whit XBMC no more need for a mouse and keyboard!

i am now going to try instal IAKTOS 10.6.3 on my laptop HP NC6320 since i got an laptop Sata disk from a friend i will start a new thread for this machine.

My wife's early 2009 Snow Leopard iMac has started failing to boot properly and I'm looking for some troubleshooting tips.

Booting from cold, it gets past the logon screen and starts loading the desktop. It's quite slow at this point, but does load all the (hundreds of!) icons on the desktop. It also tries to re-open Firefox which had a lot of tabs open. Initially it would load a Firefox window but not complete loading the internals. On one boot I think I managed to close Firefox and now it still tries to load but just displays "Firefox" in the title bar with no windows.

I can initially access a few menus, spotlight, Finder, the dock, but any further action results in a beach ball for these, and they can't be accessed again. I was able to navigate Finder to try to launch Terminal but just it just gave me the beach ball.

I've left it like this for about half an hour but it doesn't get any further and I have to force shutdown (long press of power button).

I tried booting to safe mode (holding down S on startup) but the end result was the same.

I've been able to boot to a live ubuntu USB disk and can access files on the hard disk, so I've started a backup. We have a time machine backup but it's not that recent.

I'm hoping it's just a corrupt file, but suspect it's the hard disk starting to fail.

I followed the Olarila (MaLd0N's) guide and made the Mojave USB.
I had to install the system using an invalid GPU FakeID (0x12345678) to get past the KP.
Even after installation, my system going into KP if I don't use this invalid fakeid.
With the FakeID, my system reports 7mb VRAM with Intel HD630.
I am using the DSDT from my 10.13 installation.

Used:
Whatevergreen.kext
Tried putting different FakeIDs
Put the Whatevergreen and Lilu in /Library/Extensions
Tried without Whatevergreen. The same setup used to work with 10.13.

My Laptop details are in my signature.
This is the link to the last time MaLd0N helped me get 10.13 working: https://www.insanelymac.com/forum/topic/332021-msi-gv62-7re-1013-installation/

Hi everyone. I installed MacOS High Sierra on my computer 3 months ago, in January. After a long way to get the computer fully working now I'm facing a new problem: imagine I'm working or doing something in my computer and it suddenly freezes and I have to restart it. There's no reason why the computer restarts by itself...
Here I also attach my Clover EFI folder in case you need it (it doesn't allow me to attach it so here i give you the link: https://mega.nz/#!92xCiLDZ!WY1F55ZvuP-9WW369EP9KY-3hNLt5sWUgJDxPrbgpPM .
Thank you in advance.
